Check-out this November 2016 Terebi Magazine scans featuring the fourth Gamer Rider that join EX-Aid in his fight against the Bugstars: Kamen Rider Lazer (yep Lazer, not racer).

Kamen Rider Lazer's civilian identity is Kiriya Kujo (portrayed by Hayato Onozuka). He is the mysterious man who is investigating the Bugstars incidents that sometimes occur in the hospital. He transforms into Kamen Ride Lazer Bike Gamer Level 1 by using the Bakusou Bike Gashat.

In his Level 2 form, Kamen Rider Lazer transforms into a motocross bike and will become EX-Aid's main super machine. Reminds you of a certain cop Rider that can transform into a bike eh?

So basically he's Accel, Auto Vajin, Cheeda Nick & the Deino chaser. Eh honestly just can't beat Tridoron in my opinion. Can fly, Change modes and has an AC & Heater. All it needs is a cup holder and its perfect
